We analyze bias in historical corpora as encoded in diachronic distributional semantic models by focusing on two specific forms of bias, namely a political (i.e., anti-communism) and racist (i.e., antisemitism) one. For this, we use a new corpus of German parliamentary proceedings, DeuPARL, spanning the period 1867--2020. We complement this analysis of historical biases in diachronic word embeddings with a novel measure of bias on the basis of term co-occurrences and graph-based label propagation. The results of our bias measurements align with commonly perceived historical trends of antisemitic and anti-communist biases in German politics in different time periods, thus indicating the viability of analyzing historical bias trends using semantic spaces induced from historical corpora.

本文通过研究历史语料库中编码的历时分布语义模型，重点关注两种特定形式的偏见，即政治偏见（即反共主义）和种族主义偏见（即反犹太主义），分析德国议会会议记录的新语料库，以期发现历史偏见趋势。同时，还提出了一种新的基于术语共现和基于图形标签传播的偏差度量方法。通过研究结果表明，在不同的时间段内，德国政治中存在反犹太主义和反共产主义的偏见趋势，从而证明了使用从历史语料库产生的语义空间分析历史偏见趋势的可行性。
